“…A review of ecological, behavioral, and biochemical aspects of insect HCs by Howard and Blomquist () suggested emphatically that the major function of cuticular HCs in arthropods is to serve as recognition signals between species as well as gender. The HC profile of insects is known to differ with species (Howard and Blomquist, ; Phillips et al., ) as well as gender (Nelson and Carlson, ; Nelson et al., ; Sutton and Carlson, ; Hemptinne et al., ; Ginzel et al., ). This difference in gender profile is known to be a result of (i) distinctive HCs (Nelson and Carlson, ; Nelson et al., ; Sutton and Carlson, ; Ginzel et al., ), (ii) relative abundance of same chemicals (Jackson and Bartelt, ; Jallon and David, ; Toolson and Kuper‐Simbron, ; Howard, ; Howard et al., ), or both.…”

Insect hydrocarbons (HCs) primarily serve as a waterproofing cuticular layer and function extensively in chemical communication by facilitating species, sex, and colony recognition. In this study, headspace solid-phase microextraction is employed for investigating the sex-specific volatile HC profile of five ladybirds collected from Lucknow, India namely, Coccinella septempunctata (L.), Coccinella transversalis (Fabr.), Menochilus sexmaculatus (Fabr.), Propylea dissecta (Mulsant), and Anegleis cardoni (Weise) for the first time. Major compounds reported in C. septempunctata, C. transversalis, and A. cardoni are methyl-branched saturated HCs, whereas in M. sexmaculatus, and P. dissecta, they are unsaturated HCs. Other than A. cardoni, both the sexes of the other four ladybirds had similar compounds at highest peak but with statistically significant differences. However, in A. cardoni, which is a beetle with a narrow niche, the major compound in both male and female was different. The difference in volatile HC profile of the sexes of the five ladybirds indicates that gender-specific differences primarily exist due to quantitative differences in chemicals with only very few chemicals being unique to a gender. This variation in semiochemicals might have a role in behavioral or ecological aspects of the studied ladybirds.

“…Tsetse flies of 26 species and subspecies synthesize long‐chain methyl‐branched alkanes (Carlson et al ., 1993; Sutton & Carlson, 1997). Some of these components were found to be female‐produced contact sex pheromones when synthetic analogs were tested at 1–20 µg.…”

Copulatory responses of male Glossina austeni (Newstead) (Diptera: Glossinidae), that were elicited after contact with frozen female tsetse, were not observed after solvent washing of cuticular lipids. Chromatographic analysis of extracts from laboratory-reared and field-collected G. austeni females yielded natural hydrocarbons that were highly stimulatory to males. Most of this activity was produced by compounds in the alkene fraction. Gas chromatograms (GC) contained five natural alkenes; these were separated by preparative GC for bioassays conducted in Tanzania. The two major alkenes were identified using gas chromatography-mass spectrometry (GC-MS) to be 13,17-dimethyltritriacont-1-ene and 13,17-dimethylpentatriacont-1-ene, after the samples had undergone derivatization using dimethyl disulphide and saturation with deuterium. These alkenes and natural alkanes were quantified from G. austeni of both sexes from laboratory and field samples to confirm that their presence was consistent in this species. Trials of synthetic samples resulted in the order of biological activity for the stereoisomers of 13,17-dimethyltritriacont-1-ene as follows: S,R-33:1 > R,S- 33:1 > S,S-33:1 > R,R-33:1. Dose-response data showed an ED(50) at 5 microg per treated, solvent-washed male decoy. Of the four stereoisomers of 13,17-dimethylpentatriacont-1-ene, R,R-35:1 showed the most activity. This is the first report of alkene-induced sexual activity in males of the genus Glossina.

“…Previous studies have clearly established the utility of using hydrocarbon patterns for separations between widely or closely related species of insects with subsequent use of gas chromatography and GC-MS to confirm the identities of compounds detected. Insects studied include Blattella germanica and closely related species (Carlson andBrenner, 1988, Brenner et al, 1993), 26 species and sub-species of tsetse flies (Carlson et al, 1993, Sutton andCarlson, 1997a), and tabanids (Sutton and Carlson, 1997b). Unfortunately, there was only one useful set of museum specimens of H. aenescens found at the Florida State Collection of Arthropods, as the only other specimens were in a collection from the 1950s and these flies had been dipped in solvent, probably xylene (B.D.…”

Distinctive hydrocarbons of the black dump fly, Hydrotaea aenescens (Diptera: Muscidae)

Hydrotaea aenescens (Wiedemann), the black dump fly, is a potential biological control agent originally from the western hemisphere, now found in many parts of the Palearctic region except for the United Kingdom, where it cannot be imported for any reason. A complication of classical biological control is the problem of strain identification, as one must be able to somehow mark or follow a particular strain that has been introduced into the field or is contemplated for release. Gas chromatographic analysis of the surface hydrocarbons of pooled and individual dump fly adults resulted in reproducible hydrocarbon patterns that differentiated widely distributed strains of H. aenescens and showed similarities between strains that were related. Sexual dimorphism was observed in the surface hydrocarbons. Conspecific similarities included identities of the hydrocarbons found in colony material collected worldwide, with differences being found in the quantities of compounds present.
